Abstract
The utility model discloses a graphite sealing rope, including knitted -formed's fibre layers, ramie fibers layer and glass fiber layer in proper order from inside to outside, pack a polymer fiber graphite line layer between fibre layers and the ramie fibers layer, pack the 2nd polymer fiber graphite line layer between ramie fibers layer and the glass fiber layer, be equipped with the no sulphur graphite line weaving layer of inflation outside the glass fiber layer, the outer cladding wire layer of the no sulphur graphite line weaving layer that expands, the lace has the enhancement layer outside the wire layer. This graphite sealing rope corrosion resistance and wearability, resilience can be good, the greasy property is good, and the heat dissipation is fast, and the temperature resistant degree is high and do not harm mechanical equipment.
Description
Technical field
This utility model relates to technical field of sealing technology, specifically a kind of graphite grazing rope。
Background technology
Sealing cord is generally formed by relatively soft thread braiding, is generally of good self lubricity and heat conductivity, and coefficient of friction is little, highly versatile, and flexibility is good, and intensity is high, and axostylus axostyle has the features such as protective effect。Graphite has the characteristic of high temperature resistant anti-strong acid and strong base, is best sealing material。Existing graphite material, for general quiet, movable sealing field, generally adopts cotton yarn to strengthen flexible graphite sealing rope as first-selected airtight and watertight padding, and its cost performance is of a relatively high。But due to the restriction of Plant fiber's self character, cause that its heatproof, tensile strength, comprcssive strength decline to some extent；Additionally normal flexible graphite is due to the oxidation impact of himself sulfur-bearing, causes leakage, not only flexible graphite sealing rope premature deterioration, and corrosion phenomena also occurs on the seal member surface of its contact, causes that valve rod corrodes deformation, causes bigger economic loss。
Utility model content
In order to solve above-mentioned technical problem, this utility model offer one is high temperature resistant, corrosion-resistant, mechanical strength is high, the graphite grazing rope of long service life。
This utility model is by the following technical solutions: a kind of graphite grazing rope, including the carbon fiber layer of knitting forming, ramee layer and glass layer successively from inside to outside, the first macromolecular fibre graphite line layer is filled between described carbon fiber layer and ramee layer, the second macromolecular fibre graphite line layer is filled between described ramee layer and glass layer, described glass layer is externally provided with expansion without sulfur graphite line braid, described expansion is without sulfur graphite line braid outer cladding metal wire layer, and the outer lace of described metal wire layer has enhancement layer。
Further, described tinsel is nickel wire, stainless steel silk or copper wire。
Further, described enhancement layer is made up of at least one in politef, ceramic fibre or carbon fibre。
Further, described enhancement layer is provided externally with molybdenum bisuphide coating。
This utility model advantage is: enhancement layer can significantly improve mechanical strength and the service life of sealing cord, it is possible to for High Temperature High Pressure movable sealing position, it is to avoid graphite peels off transfer。It is more corrosion-resistant that metal gauze makes sealing cord surface and sealing release portion faces, increases the service life, has both adapted to the work condition environment of High Voltage, high linear speed, strengthens again anti-corrosion capability, long service life。This graphite grazing rope corrosion resistance and wearability, rebound performance is good, greasy property is good, rapid heat dissipation, and resistance to temperature is high and does not damage plant equipment。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
1, carbon fiber layer, the 2, first macromolecular fibre graphite line layer, 3, ramee layer, the 4, second macromolecular fibre graphite line layer, 5, glass layer, 6, expand without sulfur graphite line braid, 7, metal wire layer, 8, enhancement layer, 9, molybdenum bisuphide coating。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described, but protection domain of the present utility model is not limited to this。
As shown in Figure 1, a kind of graphite grazing rope, carbon fiber layer 1 including knitting forming successively from inside to outside, ramee layer 3 and glass layer 5, the first macromolecular fibre graphite line layer 2 is filled between carbon fiber layer 1 and ramee layer 3, the second macromolecular fibre graphite line layer 4 is filled between ramee layer 3 and glass layer 5, glass layer 5 is externally provided with expansion without sulfur graphite line braid 6, expand without sulfur graphite line braid 6 outer cladding metal wire layer 7, tinsel is preferably nickel wire, stainless steel silk or copper wire, it is more corrosion-resistant that this makes sealing cord surface and sealing release portion faces, increase the service life, both High Voltage had been adapted to, the work condition environment of high linear speed, strengthen again anti-corrosion capability, long service life。The outer lace of metal wire layer 7 has enhancement layer 8, enhancement layer is preferably made up of at least one in politef, ceramic fibre or carbon fibre, mechanical strength and the service life of sealing cord can be significantly improved, it is possible to for High Temperature High Pressure movable sealing position, it is to avoid graphite peels off transfer。Enhancement layer is provided externally with molybdenum bisuphide coating 9, more wear-resisting, and anticorrosion, lubricity is better。
